The resonant frequency is a sensor characteristic. An integrated analog 1.5 kHz (−6 dB) sinc low-pass filter that cannot be bypassed limits the actual output response.

2

The temperature change is −40°C to +25°C or +25°C to +125°C.

3

temperature cycling (−55°C to +125°C and 1000 cycles), velocity random walk, broadband noise, and temperature hysteresis.

4

The VRE measurement is the shift in dc offset while the device is subject to 2.5 g rms of random vibration from 50 Hz to 2 kHz. The device under test (DUT) is

configured for the ±2 g range and an output data rate of 4 kHz. The VRE scales with the range setting.

Standby to measurement mode; valid when the output is within 1 mg of the final value.
